The National Letter of Intent (NLI) is a document used to indicate a student athlete's commitment to participating in National Collegiate Athletic Association (NCAA) colleges and universities in the United States. The NCAA Eligibility Center manages the daily operations of the NLI program while the Collegiate Commissioners Association (CCA) provides governance oversight of the program. Started in 1964 with seven conferences and eight independent institutions, the program now includes 676 Division I and II participating institutions. There are designated dates for different sports, and these dates are commonly referred to as "Signing Days". Division III institutions are specifically banned from using the NLI, or any similar document that is not executed by non-athletes at those institutions. NLIs are typically faxed by the recruited student to the university's athletic department on a National Signing Day. The NLI is a voluntary program with regard to both institutions and student-athletes. No prospective student-athlete or parent is required to sign the National Letter of Intent, and no institution is required to join the program. From Wikipedia
